The networked and intelligent promotion of rice germination and the improvement of rice production efficiency will be of great significance for the sustainable development of agriculture in China. The water temperature conditions have a significant impact on the development of rice sprouts. In order to accurately and effectively measure the temperature changes during the germination process of rice, it is necessary to monitor the rice at three different stages: soaking, bursting, and germination. Comprehensive analysis should be conducted according to the needs of rice at different stages to effectively improve the germination rate of seeds. The article designs an intelligent monitoring system for rice germination, which automatically or manually sends commands to control the entire system by monitoring the temperature and water level changes during the germination process, thereby intelligently adjusting the water temperature and water circulation process. The system design has strong operability and can achieve the goal of intelligent monitoring of rice germination system, with high practical application value.
